Abstract
The utility model provides a novel hydraulic pipe bent connector device with a locking buckle, comprising a nut sleeve and a bent connector, wherein one end of the bent connector is provided with an outer thread and the other end of the bent connector is sleeved with a nut sleeve; a circle of outer locking groove is arranged around the surface of a pipe wall of the bent connector which is contacted with the nut sleeve; a circle of inner locking groove which is matched with the locking groove is arranged around the surface of an inner wall of the nut sleeve at the end of an inner thread of the nut sleeve; the side wall of the nut sleeve is provided with a steel wire threading hole which is communicated with the inner locking groove; and an annular locking buckle is arranged in a locking channel formed after the inner and outer locking grooves are corresponding. The novel hydraulic pipe bent connector device with the locking buckle, disclosed by the utility model, has the advantages of high strength, uneasiness of thread deforming, low production cost and the like. Compared with the common bent connector pipe fitting, the novel hydraulic pipe bent connector device is longer in service life and higher in compression strength; and meanwhile, the novel hydraulic pipe bent connector device has higher use flexibility and long durability, thereby meeting the requirement of a hydraulic system on the high quality of a pipeline connector.
Description
Technical field
The utility model relates to a kind of pipe coupling, particularly a kind of novel hydraulic pipe elbow connection device that links closely with lock.
Background technique
The hydraulic tube elbow connection is a connecting pipeline or pipeline is contained in the part on the hydraulic element in the hydraulic system, its application area and extensively.The structure of existing hydraulic tube elbow connection is as shown in Figure 1; Be socketed with a nut sleeve 3 on its pipe fitting, withhold through press machine the end of nut sleeve 3, and interior receipts form a snap ring 31; These snap ring 31 down are combined in the ring-type down groove 4 on the elbow connection pipe fitting, so nut sleeve 3 and elbow connection are linked up.But a lot of shortcomings of textural existence of present elbow connection pipe fitting, its snap ring is withheld formation through press machine, so in the forming process, careless slightly, cause the internal thread distortion of nut especially easily, therefore directly influence its application.In addition, owing to the strength that elbow connection and connecting of nut sleeve relies on the snap ring deformation of nut sleeve end to form fully, so its tension, resistance to compression effect are limited, the difficult quality guarantee of joint.When in hydraulic system, using, the easy explosion in its joint causes danger, accident to take place again and again.
Summary of the invention
The purpose of the utility model is that a kind of novel hydraulic pipe elbow connection device that links closely with lock will be provided, and is yielding with the nut sleeve internal thread that solves existing fastening-pressing type elbow connection, causes the construction can't normal running; Intensity is limited, technical problems such as the easy explosion of joint.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of novel hydraulic pipe elbow connection device that links closely with lock; Comprise nut sleeve, elbow connection, said elbow connection one end has outside thread, and the other end of elbow connection is with nut sleeve; Its surface of elbow connection tube wall ring that contacts with nut sleeve is provided with a circle outer locking groove; The internal thread end place ring nut sleeve inner wall surface of nut sleeve is provided with the interior locking slot of a circle and locking slot pairing, and the nut sleeve sidewall is provided with the steel wire perforation that is communicated with interior locking slot, is provided with ring lock in the locking passage that after inside and outside locking slot correspondence, forms and links closely.
As preferably, said tight locking button is a steel wire ring.
The utlity model has characteristics such as intensity height, screw thread are not yielding, cost of production is low.More common elbow connection pipe fitting longer service life, compressive strength are higher; Have very high use flexibility and permanent serviceability simultaneously, satisfied in the hydraulic system demand pipe joint a large amount matter.
Description of drawings
Fig. 1 is the structural representation of existing hydraulic tube elbow connection;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the partial enlarged drawing at A shown in Figure 2 place;
Fig. 4 is the erection drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing, do further bright specifically to the technological scheme of the utility model.
Fig. 2 is the structural representation of the utility model.Combine Fig. 3 to know by Fig. 2, this elbow connection device mainly is made up of nut sleeve 2, elbow connection 1, tight locking button 22 etc.Wherein elbow connection 1 one ends have outside thread 11, and the other end is with nut sleeve 2, and the tube wall surface that elbow connection 1 contacts with nut sleeve 2 is provided with the outer locking groove 13 of a surrounding tube wall surface one circle.Internal thread 15 end places ring nut sleeve 2 inner wall surface of nut sleeve 2 are provided with the interior locking slot 12 of a circle and 13 pairings of outer locking groove; Nut sleeve 2 sidewalls are provided with the steel wire that is communicated with interior locking slot 12 and bore a hole 21, and the ring lock that in the locking passage 23 that the corresponding back of inside and outside locking slot (12,13) forms, is provided with a circle steel wire ring formation links closely 22.
Fig. 4 is the erection drawing of the utility model.In the production process; The nut sleeve of making 2 is enclosed within on the elbow connection 1; Let its inside and outside locking slot (12,13) coincide each other and constitute locking passage 23, one section steel wire 221 is penetrated in the locking passage 23 the rotating nut cover from steel wire perforation 21; Can, the steel wire ring so just accomplish a novel hydraulic pipe elbow connection that links closely with lock till rotating freely until nut sleeve.During use, pipe 5 is inserted in the nut sleeve 2, swivel nut cover 2 is until screwing togather sealing.
Claims (2)
1. novel hydraulic pipe elbow connection device that links closely with lock; Comprise nut sleeve, elbow connection; It is characterized in that said elbow connection one end has outside thread; The other end of elbow connection is with nut sleeve, and its surface of elbow connection tube wall ring that contacts with nut sleeve is provided with a circle outer locking groove, and the internal thread end place ring nut sleeve inner wall surface of nut sleeve is provided with the interior locking slot of a circle and locking slot pairing; The nut sleeve sidewall is provided with the steel wire perforation that is communicated with interior locking slot, is provided with ring lock in the locking passage that after inside and outside locking slot correspondence, forms and links closely.
2. the novel hydraulic pipe elbow connection device that links closely with lock according to claim 1 is characterized in that said tight locking button is a steel wire ring.
